Abstract: A rotor support system and a related method are disclosed herein. The rotor support system, in an embodiment, includes a limb coupler and a rotor coupler. The limb coupler is configured to be moveably coupled to a crossbow limb of an archery crossbow so as to enable a first movement of the limb coupler relative to the crossbow limb. The rotor coupler is configured to be moveably coupled to a rotor of the archery crossbow so as to enable a second movement of the rotor relative to the rotor coupler. The limb coupler and the rotor coupler are operably coupled.

Abstract: A gas exhaust system for a gas operated firearm may include a rear part connected to a gas block of a gas operating system, and a front part connected to the rear part. The rear part and front part have a flow path defined therealong that allows for venting of gases from the gas operating system. The rear part can have a regulating portion that regulates or control the amount of gases released from the gas operating system.

Abstract: Firearm associated electronic devices are provided. In one aspect a firearm associated device has a housing having a holding area and an opening through which a removable component may be positioned in the holding area, a door movable relative to the housing and having a door latch that moves along a path as the door moves and a housing latch movable between a first latch position where the housing latch is not in the path to a second latch position where the housing latch blocks movement of the door latch from a first range of positions where the door prevents the removable component from passing through the opening to a second range of positions where the door does not prevent the removable component from passing through the opening. A housing latch biasing member biases the housing latch into the second latch position.
